aluminium series 5

For Al-Mg series anti-rust aluminum, the strength of 5010 is higher than 3A21 , especially has high fatigue strength. Similar to 3A21,5010 has high plasticity and corrosion resistance.5010 cannot improved strength by heat treatment. It is better in Atomic hydrogen weldingand contact welding, argon arc welding with crystallization crack tendency. Alloy has good machinability in cold work hardening and half cold work hardening condition, and not good machinability in annealing state, can be polished.
